Natural rock testing is a critical procedure within the geotechnical sector of the construction industry. This process involves assessing the physical and mechanical properties of rocks, which are often employed in an array of construction applications, such as foundations, retaining walls, slope stability, and tunneling.

The primary objective of natural rock testing is to ensure that the rock is suitable for its intended purpose within a construction project. This involves evaluating characteristics such as uniaxial compressive strength, tensile strength, shear strength, specific gravity, porosity, permeability, and weathering properties. These attributes have a substantial impact on the overall stability, safety, and longevity of the structure.

Several benefits are associated with natural rock testing. Firstly, it guarantees the suitability and quality of the rock used, promoting safer and more durable constructions. Secondly, it aids in understanding the behavior of rocks under different conditions, which helps in the design and optimization of construction projects. Lastly, it leads to cost savings by preventing failures or the need for expensive repairs due to the use of unsuitable rock materials.

Natural rock testing should ideally be performed during the preliminary site investigation stage of a construction project, and also during the construction phase if required. This ensures that the rock continues to meet the necessary standards and requirements throughout the project lifecycle.

Below is the list of the most common cement tests that we undertake for our clients. All our        tests are undertaken in accordance with either the British Standard of ASTM:


  1. Uniaxial Compressive Strength Test: Assesses the maximum load per unit area that the rock can bear without fracturing.
  2. Tensile Strength Test: Evaluates the resistance of the rock to breaking under tension.
  3. Shear Strength Test: Measures the rock’s resistance to shearing stress.
  4. Specific Gravity Test: Determines the ratio of the density of the rock to the density of water.
  5. Porosity Test: Assesses the proportion of void spaces within the rock mass.
  6. Permeability Test: Determines the ability of the rock to transmit water or other fluids.
  7. Weathering Test: Evaluates the rock’s resistance to weathering or deterioration due to exposure to environmental conditions.
  8. Slake Durability Test: Assesses the rock’s resistance to disintegration when subjected to cyclic wetting and drying.
  9. Point Load Test: Measures the rock’s strength based on the force applied at a single point.
  10. Abrasion Resistance Test: Evaluates the rock’s resistance to wear and abrasion.
